    Default Android OS battery drain

    I was running an AOKP nightly no battery drain or troubles. Decided to flash Franco's kernel, after a while noticed my battery was draining rather quickly, looked and android os was way out of control. Got the newest AOKP nightly and clean flashed, problem was still there. Flashed the newest franco nightly and still happening. The phone is not going into deep sleep. No change in use or apps. Any ideas or anyone else having this problem?

    I would blame an app you have. I'm on the aokp 12/8 nightly and having no problems getting into deep sleep (screenshot shown).
    Stock kernel.

    Running 12/8 nightly with stock kernel and not having any problems with the phone entering deep sleep. Try something like Better Battery Stats and see what's keeping your phone awake.

    That is what I thought as well. When I flashed last night I did not install any apps to see if that was the problem. Still not getting into deep sleep.

    Going to do another clean install, trying a different gapps package, had been using an older one that was working fine. Maybe something with it was running out of control? Only thing I can think of, will report back.

    Any chance this could be a hardware issue? I flashed the stock image and the android os was still eating the battery. No apps installed, I am out of idea's haha.

    You're probably not giving the system and kernel time to settle nor the battery time to calibrate. After any flash you need to wait a few days or charge cycles before those stats will approach normalcy.

    I agree I'm not letting it set but this drain is new to me so I am overreacting a bit haha. I downloaded Better Battery Stats, what should I look for after I give it a day or two? Never used it, always had good battery life with my Gnex and S3 and flashed the crap out of both of those.

    After appropriate time for settling and calibrating, charge it full and leave it overnight unplugged on wifi only. Typical drain should be between 1 and 2% per hour... If it's more than that, then you can worry about it.

    The screenshots above are from AOKPs built in performance control, but it's essentially cpu spy.
